1. An optical see-through viewing device comprising a controller configured to control a display arrangement comprising an image capturing device, wherein the controller is further configured to:
a) display virtual content overlapping at least one real-life object viewable by a user's eye through the optical see-through viewing device;
b) capture a composite view of displayed virtual content overlapping the at least one real-life object, using the image capturing device;
c) determine captured virtual content based on the captured composite view;
d) determine a difference between the captured virtual content and the displayed virtual content;
e) determine modified virtual content based on the difference; and
f) display the modified virtual content.
